Answer:
44%
Explanation:
The percent increase would be calculated as the increase in insects caught divided by the original number of insects caught from the first week:
13-9 = 4 more insects caught.
4/9 = .44444
When doing percentages we multiply the decimal by 100, or move it over two places to the right, so it will be 44.4%
Numbers 4 and under round down.
Therefore,
44% is the increase
